Yeah, the scale is kind of mind-bending. You're taking something that's already extremely fragile, grinding most of its thickness away, handling it through several more process steps, and somehow doing that cheaply enough for mass-market products.
It's just crazy how far down the scale we're tickling atoms these days.
Zero chance you could do it if a human had to touch the die/chip directly during those steps.
But clean room + vacuum pick and place machine? A matter of fine tuning, and it should work just fine.
